GO Program to implement condition statement

For a better understanding of this example, we always recommend you to learn the basic topics of Golang programming listed below:

Conditional statements

Programming languages instructs the computer to make decisions on certain conditions. These decisions are made if and only if the pre-defined conditions are either true or false depending on the programmers mind. For making these types of decisions conditional statements are used.

Conditional statements in Golang

Following are the Golang Conditional statements: 

  • if statement - executes some code only if one condition is true.

If condition {
//perform some instruction
}

 

  • if....else statement - executes some code if the condition is true and executes another code if that condition is false.

if condition {
//do some instructions
}else {
//do some instructions

 

  • if....else....if statement - executes different codes for more than two conditions.

If condition1 {
//do some instructions
}else if condition2 {
//do some instructions
}else {
do some instructions
}

 

How to implement condition statement in Go Program

We are using fmt println() function for printing the string to the output screen. Here we are showing how to implement condition statements in the Go language. Here we are using a condition statement if-else. Using this check the number 11 is odd or even by finding 11%2. And also check the number 15 is divisible by 3 or not. Here the variable n is assigned with 7 and checking that the number is less than 10 and print the corresponding statement. Given below are the steps which are used in the Go program. 

ALGORITHM

STEP 1: Import the package fmt

STEP 2: Use condition statement if-else to check whether (11%2=0)

STEP 3: If true print it as even else the number is odd using fmt.println()

STEP 4: Again use if statement to check whether (15%3=0)

STEP 5: Use if to check (n := 7; n < 0) and print corresponding statement

STEP 6: Use else if to check (n < 10) and print corresponding statement

 

GO Source Code

                                          package main
import "fmt"

func main() {

    if 11%2 == 0 {
        fmt.Println("11 is even")
    } else {
        fmt.Println("11 is odd")
    }
    if 15%3 == 0 {
        fmt.Println("15 is divisible by 3")
    }

    if n := 7; n < 0 {
        fmt.Println(n, "is negative")
    } else if n < 10 {
        fmt.Println(n, "has 1 digit")
    } else {
        fmt.Println(n, "has multiple digits")
    }
}
                                      

OUTPUT

11 is odd
15 is divisible by 3
7 has 1 digit
